Chargewise
A phone app for living within a limited energy budget.
In progress
It runs the day's pacing for you — rest blocks, breathing, fluids, wind-down — as prompts on your phone and wrist. Log a flare or an over-exertion in three taps. Each morning it reads your watch's overnight data and yesterday's events, calls the day green, amber or red, and sets the cadence to match.
Over time that becomes a weekly scorecard you can share with a partner, and a summary you can hand to a clinician. The pattern behind the crashes becomes visible instead of guessed at.
Where it is, October 2026
It started in September as a handful of reminders. Ordinary reminder apps assume a day you can plan. A day that changes hour by hour breaks them.
A month on, it runs rest blocks and breathing prompts that move with the day, a morning and evening check-in, and one-tap logging for a crash or a symptom. It calls the day green, amber or red, and you can always overrule it. There is a Simple view for the days when the full one is too much, and a Garmin watch face showing heart rate, Body Battery and minutes above a set limit without opening anything.
In daily use. Next: testing on iPhone, a round of simplification, and a review by a clinician who works with ME/CFS. Then a pilot with five to ten people.
